Walking performance is usually assessed by linear analysis of walking outcome measures. However, human movements consist of both linear and nonlinear complexity components. The purpose of this study was to use bidimensional multiscale entropy analysis of ultrasound images to evaluate the effects of various walking intensities on plantar soft tissues. Twelve participants were recruited to perform six walking protocols, consisting of three speeds (slow at 1.8 mph, moderate at 3.6 mph, and fast at 5.4 mph) for two durations (10 and 20 min). A B-mode ultrasound was used to assess plantar soft tissues before and after six walking protocols. Bidimensional multiscale entropy (MSE2D) and the Complexity Index (CI) were used to quantify the changes in irregularity of the ultrasound images of the plantar soft tissues. The results showed that the CI of ultrasound images after 20 min walking increased when compared to before walking (CI4: 0.39 vs. 0.35; CI5: 0.48 vs. 0.43, p < 0.05). When comparing 20 and 10 min walking protocols at 3.6 mph, the CI was higher after 20 min walking than after 10 min walking (CI4: 0.39 vs. 0.36, p < 0.05; and CI5: 0.48 vs. 0.44, p < 0.05). This is the first study to use bidimensional multiscale entropy analysis of ultrasound images to assess plantar soft tissues after various walking intensities.

Resuscitation Guidelines

Introduction. The single most important clinically relevant cause of global cerebral ischemia is cardiac arrest. The estimated rate of sudden cardiac arrest is between 40 and 130 cases per 100.000 people per year. Almost 80% of patients initially resuscitated from cardiac arrest remain comatose for more than one hour. One year after cardiac arrest only 10-30% of these patients survive with good neurological outcome. The ability to survive anoxic no-flow states is dramatically increased with protective and preservative hypothermia. The results of clinical studies show a marked neuroprotective effect of mild hypothermia in resuscitation. Material and Methods. In our clinic, 12 patients were treated with therapeutic hypothermia. A combination of intravascular and external method of cooling was used according to the ILCOR (International Liaison Committee on Resuscitation) guidelines. The target temperature was 33oC, while the duration of cooling was 24 hours. After that, passive rewarming was allowed. All patients also received other necessary therapy. Results. Six patients (50%) had a complete neurological recovery. Two patients (16.6%) had partial neurological recovery. Four patients (33.3%) remained comatose. Five patients (41.66%) survived, while 7 (58.33%) patients died. The main cause of cardiac arrest was acute myocardial infarction (91.6%). One patient had acute myocarditis. Conclusion. Mild resuscitative hypothermia after cardiac arrest improves neurological outcome and reduces mortality in comatose survivors. .
